Condor MDR21 Pressure Switch, 100/135 PSI, 4-Port, 90 Unloader, On/Off Lever #0228DF

The Condor 21PC1E OEM pressure switch replacement is an MDR21 style, 4-port, 1/4" female NPT pressure switch with manual on/off switch and 90-degree compression style unloader valve and is preset to 100/135 PSI.

Replace the pressure switch if the compressor no longer cuts in or out at the designated pressure (PSI), if the unit doesn't turn on or off, or if there is an obvious air leak from the contacts or manifold.

If the small unloader (bleeder) valve on or under your switch leaks constantly AFTER the unit shuts off, don't replace this part, replace the in-tank check valve. Most pressure switches have a bleeder valve which has a 1/4" plastic or copper line routing to it.
